T 0 all whom 2'25 may concern:

Be it known that I, RUDOLPH CONRADER, a citizen of the United States,residing at Erie, in the county of Erie and State of Pennsylvania, haveinvented new and useful Improvements in Tank-Discharge Devices, of whichthe following is a specification.

In discharging tanks, especially large tanks of oil it is very desirableto avoid the discharge of air with the oil as such air in the pipe linesgives a great deal of trouble. lVhere there is a pronounced suction atthe discharge a suction opening is formed in the liquid leading to thedischarge through which air follows into the discharge pipe with theliquid. The purpose of my invention is to prevent this inflow of air.

The invent-ion is illustrated in the accompanying drawings as followsFig. 1 shows a plan view of the tank with my device in place therein.

Fig. 2 a section of the tank showing a side elevation of the discharge.

1 marks the tank, 2. a discharge fitting extending slightly into thetank, and 3 a discharge pipe connected with the fitting 2.

A guard plate 4: is arranged directly over the inlet to the dischargefitting 2. It is supported from the bottom of the tank by' rods 5. Theserods 5 are screw-threaded at (i for a suflicient distance to allow theadjustment of the guard so as to bring it to the height of thedischarge. The rods 5 extend into the screw-threaded rods 7 and a nut 8is provided for locking the rods in place.

The guard. plate has a pocket 9 on its under side which fits over thedischarge fitting 2 and is provided with a screen 10 along its loweredge, this screen being formed by serrations and extending upwardly toabout the point where it is desirable to discharge the tank.

In order to locate the guard in the tank I provide an attaching means11. This means is so positioned with relation to the center of gravitythat by attaching a cord to it the guard may be lowered into the tank.This is particularly desirable and necessary in oil tanks.

With this guard stationary as it is and in the direct line of thedischarge a suction opening is prevented extending upwardly from thedischarge opening to the surface of the oil. Such openings will occurwith Serial No. 365,914..

pronounced suction and with the level of the oil at a considerabledistance above the level of the discharge. The screen and guard alsoprevent the entrance of floating material on the surface of the oil tothe discharge in that the screen reaches a level below which suchfloating material can onter the discharge pipe or fitting.

lVhat I claim as new is 1. In a tank discharge device, the combinationof a tank having a discharge opening leading from the side thereof; astationary deflector over the opening preventing a direct dischar e fromabove or the formation of a suction opening in the liquid beingdischarged; and an adjustable support for the deflector.

2. In a tank discharge device, the combination of a tank having adischarge opening leading from the side thereof; and a stationarydeflector over the opening preventing a direct discharge from above orthe formation of a suction opening in the liquid being discharged, saiddeflector having a strainer along its lower edge and said strainerhaving a' level corresponding to the level of the discharge opening.

3. In a tank discharge device, the combination of a tank having adischarge fitting extending inwardly from the side of the tank; and astationary deflector over the inlet to the fitting preventing a directdischarge from above creating a suction opening in the liquid beingdischarged.

4. In a tank discharge device, the combi nation of a. tank having adischarge fitting extending inwardly from the side of the tank; and astationary deflector over the inlet to the fitting preventing a directdischarge from above creating a suction opening in the liquid beingdischarged, said dofleet-or having a socket on its under side into whichthe discharge fitting extends.

5. A deflector for tank discharge devices comprising a plate having astrainer along its lower edge; and a socket open at the bottom forreceiving a horizontal discharge fitting.

6. A deflector for tank discharge devices comprising a plate having astrainer along its lower edge; a socket open at the bottom for receivinga horizontal discharge fitting; and an adjust ble support for thedeflector.

In testimony whereof I have hereunto set my hand.

RUDOLPH CONRADER.
